Re: [Linux-cluster] Heartbeat and reboot issue



Thank you for help. Now it's fixed by modifying the libvirtd and heartbeat starting and stopping order.

Hi.

I never tried that but mybe this article can help you:

How do I create a clustered virtual service for my Xen guest using system-config-cluster?

Article ID: 5911 - Created on: Oct 28, 2007 7:00 PM - Last Modified:  Oct 28, 2007 7:00 PM

The virtual service component of Red Hat Cluster Suite allows Xen guests to be relocated or failed over among cluster members, providing high availability of that guest. In order to use virtual services the cluster must be running the Xen kernel and have shared storage, such as GFS on iSCSI or SAN. This storage will be used to share the guest image(s) and configuration files.

After storage has been set up and mounted on all nodes, the guest must be created on one of the nodes using the normal methods such as virt-manager or virt-install. See the following link for more information on setting up virtualized guests:

www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/Virtualization-en-US/index.html

Once the guest has been created and is completely shutdown, its disk image and configuration file need to be moved to the shared storage. By default, configuration files are stored in /etc/xen/ and images are stored in /var/lib/xen/images. Make sure to edit the configuration file to point to the new path for the guest image.  

Now, using system-config-cluster go to "Virtual Services" and click the "Create a Virtual Service" button on the right side. In the dialog box, the name of the Virtual Service should be the name of the guest that was created. The path should point to the directory containing the guest configuration file.

Next, click the "Send to Cluster" button to save and propagate the configuration changes to the cluster members. The guest should start automatically on one of the nodes in the failover domain

[root cluster2-1 ~]# xm list
 Name ID Mem(MiB) VCPUs State Time(s)
 clustered_guest 5 511 1 -b---- 11.5
 Domain-0 0 1509 2 r----- 6077.3

It should only be running on one node at any given time.  Note that without further configuration, guests will be restarted rather than live migrated upon relocation.

Hi,

I currently testing a two-nodes HA-cluster with DRBD (Pacemaker, Heartbeat, DRBD). When the virtual machines (with KVM) are running on one node and I halt or reboot this node, heartbeat cannot migrate the resources to the other node. Then the virtual machines are unmanaged in both nodes. I think it's related to heartbeat init scripts or some configuration is missing ?

Thank you in advance.

Best regards.
Chaibi.
